Title: Applying glass frit slurry to a seal edge of a funnel portion of a cathode ray tube
IPC: H01J9/233
Filed: 1975-08-06
Abstract: 1509718 Sealing cathode-ray-tubes SONY CORP 6 Aug 1975 [14 Aug 1974] 32887/75 Heading C1M In sealing a face plate to a funnel portion 1 of a cathode-ray-tube, glass frit is applied to the seal edge la of the funnel portion (which seal edge la is of non-uniform width-e.g. having greater width d 1  at its corners) by a method comprising: (a) mounting the funnel portion 1 on a turntable 7 with the seal edge 1a upwards; (b) positioning the nozzle 26a of a container 26 for the frit over the seal edge 1a; (c) rotating the funnel portion 1 by means of turntable 7; (d) applying a continuous flow of frit, in a constant amount per unit time, to the seal edge 1a; and (e) controlling the rotational speed of the funnel 1, so that the relative speed between nozzle 26a and seal edge la is substantially inversely proportional to the width of the seal edge la (i.e. the relative speed is lower at the corners), by detecting the width of said seal edge la, such that the frit is applied uniformly over the entire seal edge. The speed of the motor driving the turntable 7 may be servo-controlled in response to a signal representing the spacing between rollers 9, 10 which follow the inner and outer surfaces respectively of seal edge la.

Abstract: 1,072,776. Automatic exchange equipment. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Aug. 14, 1964 [Aug. 16, 1963], No. 33224/64. Heading H4K. Subscribers' keysenders transmit in two-outof-six audio frequency code by means of three generators each of which can send one or other of two 'possible tones, one generator being suppressed while the other two transmit, the receiving equipment comprising three receivers each of which discriminates between two tones of adjacent frequency. One of the receivers shown in Fig. 1 selects the tone pair by way of a band-pass filter L1, L2, C1 to C3 and discriminates between them in a resonant circuit L3, C4, tuned to the mean of the two tones. The output of a rectifier G1 or G2 switches transistor Ts2 or Ts3 to control bipolar outputs m and n which indicate which of the two tones is being received and which is not. The six tones are chosen to lie within an octave to reduce harmonic interference. An amplitude limiter is placed in the common input to the three receivers to compensate for the attenuation differences of subscriber's lines. To guard against the mixed frequencies introduced by the limiter the switching transistors Ts2 and Ts3 are provided with integrating capacitors C11 and C12. To avoid spurious responses the bipolar outputs of the receivers may be sampled only after they are fully switched.

Abstract: 1430970 Automatic control of position INTERNATIONAL BUSINESS MACHINES CORP 12 July 1973 [16 Aug 1972] 33256/73 Heading G3R To control the position of a magnetic transducer head relative to a data track of a moving record carrier, a magnetic servo head senses the positions of a pair of servo tracks associated with the data track to give a signal, which is phase shifted as a function of the deviation of the servo head from a desired central position between the servo tracks, to provide a position control signal for the servo head. As shown, the signal from the servo head is phase shifted in phase-locked oscillators 2, 3 whose output pulses are compared in phase comparator 4 e.g. an AND gate to provide the position control signal. The oscillators, also Fig. 2A, (not shown) comprise a comparator, filter, amplifier and voltage controlled oscillator. The signals on adjacent servo tracks are staggered relative to each other along the track.

Title: Beam therapy diaphragm
IPC: G21K1/04
Filed: 1956-11-01
Abstract: 802,647. Apparatus for radiation therapy. ATOMIC ENERGY OF CANADA, Ltd. Nov. 1, 1956 [July 18, 1956], No. 33411/56. Class 98(1) In a beam - limiting diaphragm, two pairs of blocks are movable towards and away from each other in directions perpendicular to the beam of radiation, each block being in sliding contact with two other blocks, and one block at least is divided along an oblique line terminating at the intersection of the inner faces of the block mentioned and of a block in contact therewith, the parts of the block being in sliding contact. As shown in Fig. 1, the diaphragm assembly 10 is rotatably mounted on an indicating- light housing 11, which in turn is mounted on a shielding container 12 for a source of radiation. A knob 15 locks the assembly. Guide plates 21, 22, Fig. 3, are mounted by tongue-and-groove connections to slide between the parallel straight edges of segmental guide plates 17, 18 mounted on the upper part of a housing 16. Plates 21, 22 have grooves 23, 24 to receive pairs of spaced rollers 25, 27 mounted on blocks 26, 28 (see also Fig. 6). Blocks 26, 28 have dovetail groove connections with a second pair of blocks 33, 34 so that each block is maintained in slidable contact with each of the other pair of blocks. The blocks rest on an upper cam plate 42 which carries rollers 43, 44 engaging grooves 45, 46 in blocks 26, 28, which cause the blocks to move towards each other or apart when the cam plate is turned by means of a knob 49 fast with a pinion 48 meshing with an arcuate rack 47 on cam plate 42. A lower cam plate 50 carries rollers 51, 52 engaging grooves 53, 54 in blocks 34, 33, which are thereby moved towards each other or apart when cam plate 50 is turned by a knob 57 fast with a pinion 56 meshing with an arcuate rack 55 on cam plate 50. The rollers 43, 44, 51, 52 are mounted on ears projecting into central circular apertures in the cam plates. Each of the blocks is divided into two parts, e.g. block 34 is divided into relatively slidable parts 66, 67, Fig. 8, with a dovetail groove connection. A screw 73, connected to a knob 71 by a shaft 72, is mounted in the part 66 and engages a nut 76 on part 67, so that the parts slide on one another when knob 71 is rotated. By rotating also three similar knobs controlling the relatively slidable parts of the other blocks, the aperture between the blocks may be made eightsided instead of four-sided, or to have an intermediate number of sides, and may be otherwise varied in shape. Manipulation of knobs 49, 47 affect both the shape and the size of the aperture. Canadian Specification 514,793 is referred to.

Abstract: 604,582. Valve generating and frequency modulating circuits ; aerials. STANDARD TELEPHONES & CABLES, Ltd. Dec. 14, 1945, No. 33903. Convention date, April 9. [Classes 40 (v), 40 (vi) and 40 (vii)] A combined oscillation generator and aerial system comprises a grounded grid oscillator with the anode circuit coupled to the cathode circuit by a feedback loop including the aerial. Valve 1 feeds over tuned circuit 4, 5 the centre tap of transformer 7, energy passing along and being radiated from the parallel wire aerial 8, 9 to the transformer 10 which presents the surge impedance to the line. The current flowing in the secondary of transformer 10 induces a voltage in the primary which travels back to transformer 7 without appreciable loss since the potentials on the two wires 8, 9 are out of phase, the secondary voltage being applied to the cathode of valve 1 to maintain oscillation. In a modification, Fig. 2 (not shown) compensating capacitors are included in the lines 8, 9 to make the velocity of the propagation of the current more nearly equal to the radiated wave velocity. The feedback from the secondary of transformer 10 also includes an adjustable artificial line. In a further modification, Fig. 3, the effective inductance of the transformer 18 is varied by applying a signal to the valve 42 to vary its impedance which shunts the secondary, thus frequency modulating the oscillations. Specification 585,746 is referred to.

Axial-flow type; balancing moving parts.- Several pressure stages of an axial-flow turbine are arranged so that the stuffing-boxes on the main shaft are subjected to practically no difference in pressure from atmosphere. The steam inlet chamber 1 and the condenser outlet 2 are both located between the end faces of the rotor and the blading is arranged in two main sets, one set 4 between the inlet 1 and the condenser 2 and the other main set having one set 5 outside the inlet 1 and the other set 6 outside the condenser outlet 2. The spaces outside the end faces of the rotor are connected by a pipe 9 and the conditions and dimensions are such as normally to ensure that the pressure in these spaces, which are of course separated from the atmosphere by stuffing-boxes (not shown), is practically atmospheric. By such an arrangement the dimensions can be selected so that the rotor is practically balanced for end thrust without the use of a dummy piston.
